Q: How to maintain glasses glasses frames: Glasses can be sent to the optical shop for ultrasonic cleaning, the general optical shop has this service. 1, tighten the screw: If the screws are loose, please get the glasses shop or yourself personally tighten, otherwise the glasses are easy to fall on the ground to break or scratched. 2, to keep clean: sweat or oil on the skin easy to corrode the metal part of the corrosive effect, cleaning glasses every day, to extend the life of the glasses very helpful. 3, the correct fold: most of the glasses are from the base side of the mirror gently folded, if the hard from the right first fold, will lead to the frame itself is not balanced, skewed, so you wear after the uncomfortable. 4, the correct mirror: wiping with a special cloth glasses. Do not touch the lens hard objects, do not wipe the lens with your fingers, please use a clean mirror cloth to wipe, reduce lens wear. 5, the correct storage: the front of the lens do not put down. If you do not, try to put glasses box, glasses, if not wear, please use a mirror cloth will be wrapped in glasses, into the mirror box, so as not to damage. 6, the right to wear: wear glasses with one hand, easy to make frame deformation. Frames if the variant, should find the local glasses master adjustment angle, do not adjust their own, so as not to break the lens, damage the frame. 7, to avoid the sun: a long time on the sun easy to place, because the frame in the light and thermal decomposition, easy to fade. Precautions: Correct care glasses will do: the lens should always wipe, the frame often care, glasses should always wear. Glasses are to help patients with myopia correction of vision tools, we have to correct care, not because of improper glasses and affect the effect of corrective vision.

Q: Is there a sheet with a flame retardant function?: The market should still have a lot of, after all, now everyone's security awareness are put up. Before the concern of the wood industry's fire-retardant board seems to be doing this, you can see.

Q: Round round plate, environmental protection plate top ten brands: Now the decoration is environmentally friendly sheet, the top ten brands are: round and round, Fuqing, Moganshan, Millennium boat, bunny, etc.

Q: What are the CTP plates?: Photopolymerized media This type of plate is usually made of aluminum, photosensitive layer and surface layer. The photopolymerizable layer is mainly composed of a polymerized monomer (+ oligomer), an initiator, a spectral sensitizer and a film-forming resin. The initiator is widely used as a multi-initiator system with high quantum efficiency. The effect of the spectral sensitizer is to effectively extend the range of the initiator to the luminescence wavelength region of the laser. It can now extend to 488nm (ion laser) and 532nm ( Multiplied YAG laser). The role of the surface layer is mainly the atmosphere of oxygen molecules separated, to avoid its into the photosensitive layer, in order to improve the photosensitive layer of the chain growth efficiency, resulting in high sensitivity. As a result of these effective measures, the photopolymerization of the direct plate of the sensitivity has been greatly improved, the minimum imaging exposure has dropped to about 10μJ / cm2, second only to the silver salt type of direct plate, and this plate structure Simple, resolution, printing rate and post-processing and conventional PS version similar or even better. Since the range of intrinsic photoreactivity of most efficient initiator systems is in the ultraviolet region and the photometric range extends to the range of the emission wavelength of the UV-LD laser, the photopolymerized direct plate will become the next generation of UV direct Preferred system, has a very good development prospects.

Q: Board grade divided into: According to state regulations, the environmental protection level of wood is divided into three categories: E0, E1 and E2. Environmental protection level E0 level: E0 level is the current national standards and related to the detection of ecological sheet of the highest environmental standards. Because the 0.5mg / l formaldehyde content is already a very safe numerical standard. According to relevant information, the formaldehyde content of drinking water is 0.9mg / l, that is, E0 grade formaldehyde content is less than drinking water. Environmental level E1 level: in accordance with state regulations, the indoor plate environmental protection level must be achieved E1 level was considered standard, that is safe and environmentally friendly, the human body will not cause harm. In recognition of the quality of the plate at the same time, the most concerned about the furniture used by the formaldehyde emission of sheet metal. E1-level environmental standards are mandatory national health standards, is mandatory "safety standard line." E1 <= 1.5mg / l, that is, 1.5mg / l formaldehyde content is in line with national standards, is environmentally friendly, harmless to the human body. Environmental level E2: E2 <= 5mg / l, E2 level of formaldehyde content has exceeded the national standard, the current production industry in the plate industry is very few E2 grade, E2 grade products must be treated after finishing to be used Interior decoration.

Q: What kind of sheet is usually used in the wardrobe?: With ecological sheet ah, is the paint-free board, do not paint, playing the wardrobe is the most environmentally friendly paint-free board, and the largest is the king of coconut, recently out of a high-end custom solid wood wardrobe.

Q: Why use office furniture: Common furniture with the plate varieties are: solid wood, fiberboard, particleboard, blockboard, plywood and so on. At present, the manufacture of office furniture is mainly used are: fiberboard and particleboard. Low-grade office furniture generally use particleboard, and medium and high-grade office furniture generally use fibreboard. Fibreboard is divided into high density fiberboard (density> 0.8 / cm3), medium density fiberboard (0.5 g / cm3 ≤ density ≤ 0.8 g / cc), low density fiberboard (density <0.5 Gram per cubic centimeter). High density fiberboard due to high density, difficult processing, and easy to nail, the installation of accessories burst; and low density fiberboard due to low density, large gap between wood fibers, easy to water swelling, resulting in surface cladding off, and even the plate disintegration, so the second The use of office furniture are less. The MDF (medium MDF), with the surface smooth, the internal structure of fine, good processing effect, with strong resistance to deformation and load-bearing capacity, And the plate holding nail ability, can be achieved many times disassembly, as in the high-end office furniture of choice. Sunlong's office furniture is used in the manufacturer's custom-made density of up to 0.76 grams per cubic centimeter of the MDF (generally medium density fiberboard density of 0.64 grams per cubic centimeter or so).

Q: Now young people who like wood color ah, but the Chinese ah, understand the wood are very old-fashioned, including the designer in the class. The The wood is divided into two one is solid wood, one is garbage wood are labeled as small sand, together with the pressure may be different. The The Speaking of low on these two types of solid wood board is equal to two pressure into the plate on the market,: First scraping putty, dry with sand can be polished after painting.

Q: Pc plate and memory board comparison, which is good?: PC board is a polycarbonate as the main component, the use of co-extrusion technology CO-EXTRUSION made of a high-quality sheet. Because of its surface covered with a layer of high concentration of UV absorbers, in addition to the characteristics of anti-ultraviolet and can maintain long-term weather, never fade. Memory plate toughness is relatively large. Select these two plates according to your needs.

Q: South Asia, Health benefits, Teng Hui FR4, which is relatively expensive?: South Asia and the benefits of the best technology, but South Asia has its own upstream industry support lower cost, cheaper, raw technology and quality control better.
